The new REST API features enabled on April 22 are so cool, you can now access all the backups created by Oracle on your own without the need to raise an SR with Oracle support. I am referring to the Artifact Snapshot taken by Oracle when there is a change to the instance.
From the Oracle Documentation,
List Backups - Only for OCI (Gen 2) Environments
In OCI (Gen 2) environments, you can list available backup snapshots archived by Oracle in the Oracle Object Storage Cloud.
You can then restore available backup snapshots (copy them to the environment), To restore backup snapshots in OCI (Gen 2) environments, see Restore Backup. After copying the backup, you can archive it or use it to restore the current environment by yourself. After copying the backup, you can archive it or use it to restore the current environment by yourself. With the List Backups and Restore Backup APIs, you no longer have to create a service request to request a backup from an OCI environment.
This API is version v2.
